glove box help

[84 400]

I have a 1984 and a 1985 chevy c10"s the 84 i got from texas this september and it is all done up with wheels tires motor and paint any way one thing that is messed up on the 84 is the glove box plastic. however my 85 DD has a perfect peice of plastic in it. However the 84 has a black interior and the 85 is tan so a complete swap is not going to happen. How do i remove the latch (or thing u turn to open the glove box)?? onecw i have the lach off it will be no problom to swich the black plastic. thanks for the help.

Also on the 84 ?How i replace the seat belts and or where could i get new ones from for a good price??? i know it is all about saftey but i really hate to spend 100+ dollars on somthing i don't even want but this truck must be safe as my little brother will be riding in it when we take it to car shows. Thanks agian
